The use of aesthetic injectables botulinum toxin, hyaluronic acid fillers, and newer biostimulatory agents has grown exponentially, often perceived as low-risk, repeatable procedures. While short-term safety profiles are well established, data on long-term and cumulative effects remain limited, especially with repeated use over years. Emerging evidence highlights concerns beyond immediate adverse events.
Delayed complications such as granuloma formation, biofilm-related infections, vascular compromise, and filler migration are increasingly reported. Additionally, repeated interventions may lead to tissue remodelling, altered lymphatic drainage, and changes in facial architecture, raising questions about the long-term impact on skin and subcutaneous integrity.
